Abstract
The present invention generally relates to hybrid power systems for vehicles. In one embodiment, the present invention relates to hybrid power systems for various types of transportation vehicles where the hybrid power systems is partially, or even totally, based on the use of at least one hydraulic system to provide supplemental, or even the primary, motion power for a hybrid vehicle. In another embodiment, the hybrid power systems of the present invention are capable of providing both motion power as well as cabin comfort heating and/or cooling. In still another embodiment, a hybrid vehicle according to the present invention comprises a power generating system and passenger cabin comfort system, wherein the power generating system comprises a thermodynamic working fluid (FA) in a first thermodynamic cycle (C1), a pump (P1), a motor (M1), a high pressure accumulator, a low pressure reservoir, and at least one heat exchanger, wherein the thermodynamic working fluid (FA) is concurrently operable to create either vehicle motion through the motor (M1) or electricity through a generator and is operable to create passenger cabin cooling or heating through the expansion or contraction of the thermodynamic working fluid (FA).
